For submarines, enemy aircraft and helicopters are a huge threat, but the means of attacking aircraft and helicopters from submarines have been very limited in the past.
For example, the “latent-to-air missile” disclosed in Patent Document 3 can attack an aircraft or helicopter from a submarine, but has the following problems.
(1) Submarines give top priority to concealing their existence. However, since the above-described submarine missile will start ascent immediately after being ejected from the submarine, the enemy will discover the missile that has emerged, and it will become clear that there is a submarine nearby.
(2) Due to the structure of the missile, a propulsion device (rocket motor, jet engine, etc.) and a guidance device (actuator, steering blade, etc.) are indispensable, and the size and weight increase. Therefore, in order to launch a missile from a submarine, a torpedo launch tube or a large facility equivalent to this is required, and the number of missiles mounted on the submarine is limited to a small number similar to that of a torpedo.
In addition, since the missile requires a complicated propulsion device and a guidance device, the manufacturing cost is very high.

  The present invention has been developed to solve the above-described conventional problems. In other words, the object of the present invention is to equip a submarine and launch it from underwater and attack a flying aircraft or helicopter.After launching it, it is possible to safely separate from the injection point while keeping the submarine's presence secret, To provide an air-to-air ultra-high-speed projectile that can be reduced in size and weight so that it can be ejected from a small shooter, etc., compared to a torpedo launch tube, and that can reduce costs relatively, and an anti-air attack method using the same. It is in.

The motor control unit feedback-controls the rotation direction and rotation speed of the motor according to the depth detected by the water pressure sensor,
An air-to-air ultra-high-speed flying bullet is provided in which a predetermined depth is maintained by the depth maintaining device for a predetermined time after being injected into water, and then the containment container is expanded or separated and the floating bag device is expanded and deployed.

Moreover, according to the present invention, there is provided an anti-air attack method for attacking a target in flight using the above - mentioned anti-air super high-speed flying bullet from a submarine,
An injection step of injecting anti-aircraft ultra-high-speed flying bullets from the submarine into the water,

An air-to-air attack characterized by having an attacking step of holding a warhead device in a stable position on a float apparatus and actuating the warhead and firing a self-forged bullet toward the target after the capture sensor captures the target A method is provided.

  According to a preferred embodiment of the present invention, the warhead device includes a warhead that fires an ultra-high-speed self-forged bullet, a capture sensor that is attached to the warhead and captures a target located on the flight trajectory of the self-forged bullet, A scanning device that turns the warhead within a predetermined angle range; and a firing control device that fires a self-forged bullet by the warhead after the target is captured by the capture sensor.

  In addition, the containment vessel has a separation device that unfolds or separates part or all of the containment vessel to expose the warhead device.

According to the configuration of the present invention, an anti-aircraft ultra-high-speed flying bullet is injected into the water from the submarine, ascends, captures the target by the warhead device, and fires the self-forged bullet toward the target. Can attack aircraft and helicopters in flight.
In addition, since the depth maintaining device is provided and the predetermined depth is maintained for a predetermined time after the injection into the water, the submarine can be safely separated from the injection point while keeping the presence of the submarine.

  Furthermore, the warhead device is composed of a warhead, a capture sensor, a scanning device, and a firing control device, and after the target is captured by the capture sensor, a self-forged bullet is fired by the warhead, so that no complicated propulsion device and guidance device are required. Yes, it can be reduced in size and weight so that it can be emitted from a shooter or the like that is smaller than the torpedo launch tube, and there are few complicated devices and the cost can be reduced relatively.

In other words, in the warhead device of the present invention, the power body (self-forged bullet) that defeats the target is fired by the firing of the glaze and flies with the inertial force at the time of launch, so no propulsion device is required. Since it is fired at the moment when the target is captured and hits the target without guidance, a guidance device is unnecessary.
Therefore, it can be reduced in size and weight, and can be injected from a simple and small shooter.
Also, the depth maintenance device can delay ascent to the sea for an arbitrary time, during which time the submarine can be sufficiently separated from the launch point.

A wide range of attack areas can be constructed at once by storing multiple (many) anti-aircraft high-speed flying bombs in an injection container having a shape equivalent to a torpedo and simultaneously deploying them on the sea surface.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In each figure, common portions are denoted by the same reference numerals, and redundant description is omitted.

FIG. 1 is an overall configuration diagram of an anti-aircraft ultra high-speed flying bullet according to the present invention. In this figure, (A) shows the form when accommodated in a submarine, and (B) shows the form when deployed on the water surface.
The anti-aircraft high-speed flying bullet 10 of the present invention is a device that injects underwater from a submarine (not shown) and attacks a target in flight. As shown in FIGS. 1A and 1B, the warhead device 12 and the floating bag device 20 , A storage container 26, a depth maintaining device 30, and a levitation control device 40.

  The warhead device 12 has a function of capturing a target (an enemy aircraft or helicopter) and firing the self-forged bullet 11 toward the target. In this example, the warhead device 12 includes a warhead 13, a capture sensor 14, a scanning device 15, and a firing control device 16.

The warhead 13 fires the self-forged bullet 11 by the ignition of the glaze, and makes it fly at inertia at high speed toward the target, thereby destroying the target.
The self-forged bullet 11 is different from a missile or the like, and the flying body is only a molded metal piece and is relatively small and light, but its speed is high and the kinetic energy proportional to the square of the speed is enormous. , Has a great destructive power.

The capture sensor 14 is attached to the warhead 13 and captures a target located on the flight trajectory of the self-forged bullet 11.
The capture sensor 14 is preferably an infrared sensor or a laser range finder, only one of them.
The infrared sensor is directed in the direction in which the self-forged bullet 11 flies, and the target enters the flight trajectory and detects heat generated by the target.
The laser range finder is directed in the direction in which the self-forged bullet 11 flies. When a target enters the flight trajectory, the laser range finder detects the presence of the target by a reflected wave and simultaneously detects the distance to the target.

  The scanning device 15 turns the warhead 13 together with the capture sensor 14 with a predetermined inclination angle. The predetermined inclination angle is, for example, a circular search by inclining and turning 30 degrees about the upward vertical axis.

  The firing control device 16 is a microcomputer, for example, and recognizes the target from the detection signal of the capture sensor 14 and fires the self-forged bullet 11 by the warhead 13.

  The warhead device 12 further includes an activation acoustic sensor 17, and after the sound generated by the target (an enemy aircraft or helicopter) is detected by the activation acoustic sensor 17, the entire warhead device 12 is activated. Good.

  With the configuration of the warhead device 12 described above, the self-forged bullet 11 is fired by the firing of the glaze and flies with the inertial force at the time of launch, so that a propulsion device is unnecessary. In addition, since the self-forged bullet 11 is fired at the moment when the capture sensor 14 captures the target and hits the target without guidance, no guidance device is required. Accordingly, the warhead device 12 can be reduced in size and weight.

The buoyancy device 20 is an inflatable buoyancy body, is a flexible and folded airtight and pressure-resistant bag, is attached to the lower part of the warhead device 12, and is inflated and deployed by gas pressure. .
Further, due to an increase in buoyancy due to expansion and deployment, the warhead device 12 is levitated to the water surface, and the warhead device 12 is held in a stable posture thereon. In addition, the float apparatus 20 may be inflated and deployed after floating on the water surface.
Here, the “stable posture” refers to a posture in which the inflatable buoyant body floats on the water surface and keeps the swivel axis of the scanning device 15 substantially vertical although it swings due to waves and undulations on the water surface.

The storage container 26 accommodates the warhead device 12 and the float device 20 inside, accommodates in the submarine, and can be ejected into water from a shooter or a torpedo tube. In this example, the shape of the storage container 26 is an elongated cylindrical shape whose upper and lower ends are semicircular. However, the storage container 26 can have any shape as long as it can be injected into water.
Further, the storage container 26 includes a detaching device (not shown), and by operating the detaching device, a part or all of the storage container is developed or separated to expose the warhead device. The disconnecting device may be an actuator that is actuated by glaze ignition, solenoid, electric motor or the like.

The depth maintaining device 30 is attached to the storage container 26 and has a function of maintaining a predetermined depth.
In this example, the depth maintaining apparatus 30 includes a water pressure sensor 32, a propeller 34, a motor 36, and a motor control unit 38.
The water pressure sensor 32 is a water pressure gauge and detects the depth. The propeller 34 is a rotating blade that rotates about the axis (that is, the vertical axis) of the containment vessel 26, and generates a lifting force by forming a downward or upward water flow depending on the rotation direction. The motor 36 is an electric motor or a fluid pressure motor, and drives the propeller 34 to rotate. The motor control unit 38 supplies a power source (power source or pressure source) to the motor 36 and controls the motor 36.
With this configuration, the motor control unit 38 can feedback-control the rotation direction and rotation speed of the motor 36 in accordance with the depth detected by the water pressure sensor 32 to maintain a predetermined depth set in advance.

  Note that. The depth maintaining device 30 is not limited to the above-described configuration, but supplies gas (air, nitrogen, etc.) into the storage container 26 or discharges gas or water from the inside, thereby increasing the buoyancy of the anti-aircraft high-speed flying bullet 10. The structure which controls and maintains the depth may be sufficient.

  The levitation control device 40 is, for example, a microcomputer, and controls the floating bag device 20, the storage container 26, and the depth maintaining device 30, and after injecting into the water, maintains the predetermined depth for a predetermined time by the depth maintaining device 30, and then disconnects. The storage container is expanded or separated by the device, and the float bag device 20 is expanded and deployed. Note that the operation timing of the separation device may be either water or water.

In this example, the attachment position of the levitation control device 40 is a lower portion of the buoyancy device 20, but may be another position as long as the buoyancy device 20, the storage container 26, and the depth maintaining device 30 can be controlled.
Further, the above-described launch control device 16, motor control unit 38, and levitation control device 40 may be integrated and replaced with a single microcomputer or computer.

FIG. 2 is a usage state diagram of the anti-aircraft ultrahigh-speed flying bullet of the present invention, and shows a state in which the bag apparatus 20 is inflated and expanded and floats, and the warhead apparatus 12 is held in a stable posture thereon.
The warhead device 12 starts to operate immediately after it floats on the water surface and enters this state. The operation may be started after the activation sound sensor 17 detects the driving sound of the target (an enemy aircraft or helicopter).

When the operation starts, the scanning device 15 turns the warhead 13 together with the capture sensor 14 with an inclination angle of 30 degrees about the upward vertical axis.
By this turning and swinging, the airspace above it can be monitored by the capture sensor 14 on the cone.
When the target 1 (an enemy aircraft or helicopter) is captured by the capture sensor 14, the warhead 13 is actuated by the firing control device 16 to fire the self-forged bullet 11 at that moment.
As described above, the self-forged bullet 11 is different from a missile or the like, and the flying body is only a molded metal piece and is relatively small and light. However, its speed is high, and the motion is proportional to the square of the speed. The energy is enormous and it has a great destructive power. In addition, since the target is reached instantaneously after launch, the target travel distance is small, and a high accuracy rate can be obtained even in inertial flight without a guidance device.

FIG. 3 is an explanatory diagram of the anti-air attack method using the anti-air ultra high-speed flying bullet of the present invention.
As shown in the figure, the air-to-air attack method of the present invention operates sequentially in each step of the injection step S1, the depth maintenance step S2, the expansion and deployment step S3, and the attack step S4.

In the injection step S <b> 1, the anti-aircraft ultrahigh-speed flying bullet 10 is injected from the submarine 2 into the water. In this injection, it is preferable that the anti-aircraft ultra-high-speed flying bullets 10 are individually ejected from a small shooter. However, a plurality (multiple) anti-aircraft ultra-high-speed flying bullets are stored in an injection container equivalent to a torpedo, and simultaneously injected into water. Also good.
In the depth maintaining step S2, a constant depth is maintained for a preset time. Although this time and depth are arbitrary, it is good to set to the time which the submarine 2 can fully separate from an injection point after injection. Further, the depth is preferably set so that the anti-aircraft ultra high-speed flying bullet 10 cannot be found from an enemy aircraft or helicopter.

In the expansion / deployment step S3, after maintaining the predetermined depth for a predetermined time, the storage container 26 is expanded or separated, and the floating bag device 20 is expanded and expanded. The expansion or separation of the storage container 26 and the expansion and expansion of the float bag device 20 are preferably performed after floating on the sea surface, but may be performed underwater. Next, a stable posture is obtained by the float bag device 20.
In attack step S4, after the activation acoustic sensor 17 detects the target 1, the entire warhead device 12 is operated, and at the moment when the capture sensor 14 captures the target 1, the warhead 13 is activated and the self-forged bullet 11 is targeted. Launch toward the target and penetrate and destroy target 1 with kinetic energy.

According to the configuration of the present invention described above, the anti-aircraft ultra-high-speed flying bullet 10 is ejected from the submarine 2 into the water, ascends, captures the target 1 by the warhead device 12, and fires the self-forged bullet 11 toward the target. You can equip a submarine and attack a flying aircraft or helicopter from underwater.
Further, since the depth maintaining device 30 is provided and the predetermined depth is maintained for a predetermined time after the injection into the water, the submarine 2 can be safely separated from the injection point while keeping the presence of the submarine 2 in the meantime.

  Further, the warhead device 12 includes a warhead 13, a capture sensor 14, a scanning device 15, and a firing control device 16, and the self-forged bullet 11 is fired by the warhead at the moment when the target 1 is captured by the capture sensor 14. A small propulsion device and a guidance device are not required, and the size and weight can be reduced to such an extent that it can be emitted from a shooter or the like that is smaller than a torpedo launch tube.

That is, in the warhead device 12 of the present invention, the powerful body (self-forged bullet 11) that defeats the target 1 is fired by the firing of the glaze and flies with the inertial force at the time of launch, and therefore no propulsion device is required. Is fired at the moment when the capture sensor 14 captures the target and hits the target without guidance, so a guidance device is unnecessary.
Therefore, it can be reduced in size and weight, and can be injected from a simple and small shooter.
Further, the depth maintenance device 30 can delay ascent to the sea surface for an arbitrary time, during which the submarine can be sufficiently separated from the injection point.

  If the warhead equipment 12 that has completed its mission without attacking the target is left as it is, there is a risk of attacking an aircraft other than the attack target. By self-destructing, the anti-aircraft high-speed flying bullets can self-sink.

  In addition, this invention is not limited to embodiment mentioned above, Of course, it can change variously in the range which does not deviate from the summary of this invention.
